Product Description

The Seimitsu PS-14-G is a solid color 30mm pushbutton designed to snap into a thin (1.3mm or .051") metal panel. It has a noticeably flat plunger top, preferable to some who don't like the convex shape of other Japanese pushbuttons. The PS-14 G uses the Seimitsu PS-14-G Button Micro Switch. Please see our product photo gallery for full specs.

Bundle with MM9-4 High Tension Button Spring and Save

The MM9-4-25N adds an extra .08 LBF (pounds force), for a total of 0.28 LBF. The result is a light, but firm button input requirement that accelerates its the button cap's return to neutral.

The MM9-4-50N adds an extra .16 LBF (pounds force), for a total of 0.34 LBF, resulting in a much firmer button input requirement that quickly pushes the button cap's to neutral position, ready for the next press.

This is desirable to some who appreciate using more deliberate input force and a bit less sensitivity than Sanwa's SW-68 offers. Now, you can save 25 cents off the regular price of the MM9-4 series spring when you choose one of the high tension springs from the options list.

24 vs 30mm

When processing orders, a frequent mistake we found among new players is choosing the wrong size for action buttons, such as punch and kick.

Within the fighting game genre, Japanese arcade buttons commonly consist of two diameter sizes: 24 millimeter and 30 milllimeter (mm). In most configurations, 30mm represents your action button. These are front facing, appearing most prominent on your Fightstick control panel. Option button, such as "Start", "Select", or more recently "Option", "Touch", or "Share" are usually 24mm.

Below is a visual representation of a common Fightstick control panel. Throughout this article, we will mark 24mm in green, and 30mm in Orange.

Checking the Proper Size

Another way that players can misinterpret the pushbutton size is by measuring the pushbutton plunger. Have a look at the diagram at right.

The plunger - the part that you press down to represent an input - is 25mm or a bit smaller in most 30mm pushbuttons. Often this leads to the conclusion that one needs a 24mm button and not 30mm.

Similarly measuring the button rim can lead to confusion, as it is intentionally larger than the button hole it is placed in. You don't want to use these measurements. Instead, review the button housing diameter, or the hole the button will be placed in. You can do this with a caliper - a digital caliper is often quite helpful for this and other arcade-related projects.

Control Panel Configuration

Most Fightsticks from MadCatz, Hori, Qanba, and similar will use these two sizes. How the buttons are used will depend on the model joystick that you own. Over time, we'll provide example configurations for specific popular Fightstick models and arcade cabinets using the color key for 24mm (green) and 30mm (orange). We'll also expand the key for future models if another size is introduced, and we offer for sale.
